Up-to-Date Guidance from One of the Foremost Members of the R Core TeamWritten by John M. Chambers, the leading developer of the original S software, Extending R covers key concepts and techniques in R to support analysis and research projects. It presents the core ideas of R, provides programming guidance for projects of all scales, and introduces new, valuable techniques that extend R.The book first describes the fundamental characteristics and background of R, giving readers a foundation for the remainder of the text. It next discusses topics relevant to programming with R, including the ap...

"Chambers, a consulting professor in the Department of Statistics at Stanford University, indicates that the purpose of this book is to encourage and help individuals develop extensions to the R software. Obviously, one must have experience using R and ideas for extensions that he or she would like to make, such as adding some functions or developing packages of different degrees of sophistication. The book contains three fundamental principles: every element that exists within R is an 'object,' all elements that happen within R are a 'function' call, and 'interfaces' to other software are part of R. These principles are then expanded in sections about ideas and history, aspects of programming in R, object-oriented programming, and

interfaces from R to other software. As Chambers is the creator of the S software (the predecessor of R), any of his works are considered important and should be acquired by all statistical science libraries. This book will be a valuable guide for individuals who wish to develop their own extensions to R, whether at a modest or a more ambitious level.

Summing Up: Highly recommended. Lower-division undergraduates and above; faculty and professionals."

~R. Bharath, Northern Michigan University

". . . Chambers provides valuable insight into some of the thinking that led to major contributions to R's development. For example, one section is divided thoughtfully into three themes, namely, programming in the small, in the medium, and in the large. Each theme is used to introduce and illustrate different aspects of the language, from the point of view of the kinds of activities that cluster within the themes, and here the book really shines. It is a pleasure to see how a crafter of tools thinks deeply about how the tool will be used."

~Andrew Robinson, University of Melbourne

"Doug Bates once said to me that 'There's no doubt about John Chambers. He can see much further than the rest of us.' This latest book is yet another illustration of that incisive observation. It is fundamentally a book about perspectives and strategies. It gives a deep insight into the R landscape, its background and structure, and shows how users can work with R when they need to extend its facilities."

~Biometrics, June 2017

"This book is a must-have for anyone with a deep interest in statistical computing . . . you will learn some of the theory that underpins R, and see the directions in which you can extend it to solve your problems . . . it does give you powerful ways of thinking about programming on a large scale that will pay off as you tackle more ambitious projects."

~Hadley Wickham, Journal of the American Statistical Association

" . . . any new book by John Chambers, the main developer of the original S language from which R derives, commands particular attention. . . Experienced R programmers will want a copy. R users seeking a deeper understanding of the internal structure of the language will also benefit, especially regarding aspects of functional programming and object-oriented computations.
